first, those in which the rim is detachably.

mounted-upon the disk and second, those in which the rim is permanently secured to the disk by means of rivets or welds. This invention relates to disk wheels of the irst type and its chief object is to provide means for demountably connecting the rim to the disk .which means permit a certain relative rocking. of the rim and the disk and at the same time positively 5insure the correct location of the rim on the disk. Y

A further object is to provide a disk wheel in which the-disk has, adjacent the rim, an annular band, the face of which band lies in a plane at right angles to the wheel v axis behind the line of the center of the wheel so that the valve stem, through which, under ordinary conditions, the center line of the wheel passes, lies entirel in front of the disk and so thatrno radial depression or other deformation of the disk band is necessary in order to accommodate the valve.-

Other objects will appear from the details of construction set forth in the following specification and in the accompanying drawing which forms a part thereof and in which- Figure 1 is a front elevationv of a disk wheel embodying one form of this invention;

In order to facilitate the description certain terms are used in the specification and claims with respect to which arbitrary nieanings have Abeen applied. Thus the term with the rim to denote the face of the rim nearest the axle in other words that portion of the rim With which the disk engages. The terms upper lower below used `with reference to' the hub regardless of the actual relative positions that the parts so designated assume as the wheel is rotated.v `Hence a part nearer the hub than another part is described as being below or lower7 Athan the other.

Referring to the drawing it will be n0- ticed that the disk wheel comprises a disk 10 and a rim -11. The rim 11 is demount- `is an annular bead 1.5 the outer face 16 of which'is perpendicular to the base of the rim 11 and the inner face 17 of which is inclined to the rim at approximately' thirty (30) degrees. This bead 15 is located on the inner half of the rim 11 and is so positioned that the outer face 16 lies in a plane parallelI to and a specified distance behind the center plane 18 of the wheel. The disk 10 is formed ladj acent the rim 11, with an annular band 19 which liesin the same plane as the face 16. At the outer edge of the disk is a flange 20 suitably inf clined so that when` the isk and rim are assembled the flange 20 will contact with the face 17 of the bead-1b. The locking ring 12 is of channeled cross section havino an upper leg 21 and a lower leg 22 both tlegs being of the same depths, and when K.assembled the upper leg 21 bears against the face 16 of the bead 15 while the lower leg 22 bears against the band 19 of the disk 10. When the nuts 14.- are tightened on under side has been used in connection are llO

the bolts 13, it is obvious that the-pressure of thevring 12 will seat the rim 15"upon the liange in the proper position, with lthe face 16 of the lbead in the plane of the band 19 of the disk. Thus, by the construction above set forth the proper location ofthe rim upon the disk is insured under all conditions. The advantages of such a construction are believed to be obvious and need notlbe pointed out in detail.

Throughthe base of the rim 11 is provid- I ed a hole 23 through which the valve stem 12 are cut away at 25 and 26 and when the parts are assembled the valve stem 24will e located in these cut away portions 25, 26.

In order to secure the tire firmly to the rim, it is the usual custom to employ a locking nut 27 which is threaded upon the valve stem 24 and which, in a wooden wheell for example, bears against the under side of the felloe. In place .of the felloeof a wooden wheel and to insure the proper rigidity of the valve stem 24, the disk band 19 is out and depressed at 28 to provide a pocket 29. The distance of the edge 30 from the rim is the same as the width of the locking ring 12 and thus the nut 27 will bear against the edge 30 of the band 19 and also against the legs 22 of the ring 12.

The pocket 29 in the disk also permits the application ofanair tube to the end of the valve stem without in any way scarring the surface-of the disk. Furthermore, this de'- pression permits the application of the valve cap 31' so that the same valve stem can be used in this particular type of disk wheel here shown as in a wooden wheel. Thus it is possible to employ any type of valve in connection with this disk wheel and moreover, it is not necessary to change in particular `the valve stem construction.

' The particular type of rim shown is of the straight `side split ring variety the sections 32, 33 being joined at the split 34 by a lug 35 which is carried by the section 32 and which enters a slot in the section 33. This lug 35 has a tapered face 36 which as indicated on Fig. 6 coincides with the tapered face 17 of the bead 15 and terminates at the inner edge of the bead. The flange 20 thus seats against the lug as well as against the bead.

In order to prevent any relative rotation between the disk and the rim a notch 37 is provided in the leg 21 of the lock ring 12 the sides of which engage the sides of the lug 35. Thus all power is transmitted between the disk and the rim by the lug 35 ring 12 and bolts 13 and any deformation of the Bange 20 of the disk is avoided.

Lava-ses inclined flange-at the outer edge, a demountable rim, a bead 'on the underside of' said rim, the outer-face of said bead being perpendicular to the base of said rim in the plane of said annular band, and the inner face of said bead being inclined toA said base, whereby, when the wheel is assembled, the inner face of the bead rests upon the inclined flange of the disk, and a clamping ring having vupper and lower legs of the same depth for securing said rim in position upon said disk, the upper leg of said rin bearing against the outer face of said bea and the lower leg bearing against said annular band.

2. In a disk wheel, a rim, a disk having a continuous annular band adjacent said rlm,

vand in a plane parallel to the center plane of the wheel, a bead on the underside of said rim, one. face of which bead is lperpendicular to the base of said rim and lies in the same plane as the band on said disk, the plane of said band and bead being so located with reference to the center plane of the wheel that the valve stem of a tire on said rim, which stem is in the center plane of the wheel, projects from said rim in front of and out of contact with said bead and band and a clamping ring for securing said rim to said disk, said ring comprising upper and lower legs, the inner leg bearmg against said annular band and the upper leg bearing against the perpendicular-face of said bead and notches through said upper and lower legs for the valve stem.

3. In a disk wheel, a Vsplit rim, a lug on the underside vof said rim for holding the sections of the rim in functioning position, a bead on the underside of said rim termlnating at said lug, a disk having a flange ,with which said bead engages, clamping means for holding said rim to said disk, and means for securmg said clamping means .to said disk, said clamping means also en` gaging said lug and preventing relative rotation between said disk and said rim.

4. In a disk wheel, a rim, a'disk having adjacent the rim an annular band in a plane parallel to the center plane of the wheel, a valve hole in said rim in the center plane of the wheel through which hole the valve stem of a pneumatic tire on Said rimprojects, the band of said disk being so located behind the center plane of the Wheel that the valve stem is in front of and out 0f contact with said band, a clamping ring for securing said rim tosaid disk, and Phaving a notch in which the valve stem lies, and a pocket in said disk below said band the upper edge of said pocket being the same distancepfrom the rim as the lower edge of said clamping ring whereby the lock nut on the valve stem seats against the underside of said ring and the edge of said pocket.

5. The combination with a Wheel having an inwardly inclined peripheral portion of a demountable rim having an annular bead on its underside behind 'the median plane of said rim, the outer face of said bead being the outer. face of saidrim bead and said g Wheel..

In testimony whereof I have aflixed my signature.
